Legumes are the most important source of food and fodder but due to climatic changes and global warming; crops are consistently exposed to environmental stresses such as low water shortage, high salinity, mineral toxicity and deficiency, extreme temperatures, etc. Drought is undoubtedly the major constraint limiting plant growth and crop productivity worldwide. The present study was conducted to assess the effect of drought on the growth of plant and productivity in three different mungbean varieties [Vigna radiata (L.) Wilczek] i.e. IPM 02-3, RMG 975 and IPM 02-14. The studied varieties exhibited significant variation in plant height, root length, pod length, pods/plant, fresh weight of shoot, root and nodule, dry weight of shoot, root and nodule, number of leaves/plant, plant leaf area, relative leaf water content (RLWC) and initiation day of flowering. The effect of drought can better seen at the flowering stage and pod development stage that ultimately reduces crop productivity. The deleterious effect of drought in terms of morpho-physiological properties studied as above was more prominent in the variety IPM 02-14 in comparison to RMG 975 and IPM 02-3. It can be concluded that varieties IPM 02-3 and RMG 975 are better adapted to drought condition.
